SkinLab

SkinLab is a browser-based biophysical model of human skin built by dermatologist Magnus Lynch. His words on how it happened: "Built with Claude Code over five days." (He has form here — a year earlier he posted a skin-cancer quiz he "vibe coded with Gemini 2.5 Pro.")

The model is serious. A 40 × 40 × 9.75 mm skin block rendered from 1.2 million voxels, running entirely in WebGL with three.js and no backend. Every constant comes from published papers. You can press the skin and watch it deform, cut it with a scalpel at a chosen depth, punch a cylindrical wound, ablate without depth limit, fire a laser in an array of microcolumns, then scrub a slider and watch the scar heal over a full year — granulation advancing from the walls, the scar contracting and pulling surrounding skin in, flat, hypertrophic or atrophic scar types behaving differently.

The detail that elevates it beyond a toy: a "Validate model" button runs five scenarios against published behavior and clears the block, and a "Scar report" scores your scars in the terms the literature uses. It is a genuine research-grade simulation, built in five days by a doctor who does not write production code, and it runs in any modern browser.
